Question

Unghiurile AOB si BOC sunt adiacente complementare si 3xm(AOB) =2xm(BOC).Aflati m(AOB) si m(BOC)

Answer 1

m(<AOB)= a

m(<BOC)= b

a+b=90

3mxa=2xmb<=> a=2xmb/3mx (mx se simplifica cu mx) <=> a=2/3b

                                                                                              a=90-b <=> 90-b=2/3b <=> 90=5/3 b <=> 5b=270 <=> b=54 de grade

a=90-54=36 de grade
